accuracy in tlie determination of the known species and dis-
crimination of those which are new, was obviously impossible
without a considerable general knowledge of Indian botany,
and a comparison with English herbaria, of which Dr. -Miquel
had not the opportunity of availing himself.
M. De Vriese's labours include various memoirs on Malayan
Island plants; And his recent monograph of M arattlamt> is
a work of great labour, but his views of the limits of species
are wholly at variance with our experience.
Hasskarl, the author of the ' llortus Bogoriensis' a cata-
logue (with occasional notes and descriptions of new species)
of the plants cultivated in the Govern men* Botanical (Sanlon
of Buitenzorg, near Baiavia (published in Batavia in 1814),

'Plantai Javauicse rariores' (Bcrli.ii, 1818),
The f JBuciiquise llimikiame/ of Presl, is a folio volume with
plates, devoted to the materials collected by Ilu'iikc, who WOK
employed in the Spanish service, and collected in America and
Manilla; the Indian plants described are few, and the descrip-
tions and identifications far from satisfactory.
The 'Mora dc Filipinas' of Father Blanco, published at
Manilla in 1837, is a botanical curiosity, written in Spanish.
The descriptions are intelligible, but, from the author'^ want
of acquaintance \rith scientific works, so many wdl known
plants are treated as new, that we consider it undesirable to
devote time to their identification.
Turning to the west of India, we find ourselves treading
upon the limits of other- floras, that have been more or less
perfectly elucidated, in works which we have couHtamiy quoted
in the Flora Inclica: of these, the most important are the
writings of Ledebour, especially the * Flora ilossieu/ * Flora
Altaica/ and * Iconcs Flora* Kossicse/ The € Flora Kmsica'
contains descriptions of the plants of the whole Ku&tiau do-
minions, which may be said to be very satisfactorily explored,
botanically, especially considering their enormous area. The
majority of our Afghan and Tibetan plants, being also natives
